He’s a congressman (from The Woodlands), the top House Republican on the congressional Joint Economic Committee, a veteran member of the House Ways & Means Committee and a former MVP of the annual congressional baseball game.

Add to that list “official Republican fact-checker.”

Brady yesterday took on the task of fact-checking White House Chief of Staff Jack Lew’s claim “that for every dollar of new revenue, the budget [proposed Monday by President Obama] includes $2.50 in spending cuts.”

“When we fact checked this claim it quickly earned a rating of ‘untrue,’” Brady concluded, sounding very much like the nonpartisan fact-checking site PolitiFact. “The White House counted spending cuts already enacted into law and also disguised interest savings on tax increases as spending cuts. A math teacher would call that cheating.”

Brady concluded that the Lew formula counted as new spending cuts $1.72 trillion in cuts that already have been implemented as law and approximately $800 billion in savings on interest on the national debt created by their cuts.

The Texas lawmaker and his fellow Joint Economic Committee Republicans suggested a different spending-cuts-to-revenue ratio.

“The true ratio is a mere 83 cents in spending cuts for every dollar in tax increases, which means that President Obama wants to force hardworking taxpayers to tighten their belts before Washington tightens its belt,” Brady argued. “That’s not fair, especially when President Obama wants to take more of your income to fund a bloated, unsustainable government.”
